Dairying, diseases and the evolution of lactase persistence in Europe
In European and many African, Middle Eastern and southern Asian populations, lactase persistence (LP) is the most strongly selected monogenic trait to have evolved over the past 10,000 years1. Although the selection of LP and the consumption of prehistoric milk must be linked, considerable uncertainty remains concerning their spatiotemporal configuration and...Evershed, Richard P ; Davey Smith, George ; Roffet-Salque, Mélanie ; Timpson, Adrian ; Diekmann, Yoan …

Characterisation of some species groups of Brachymeria (Hymenoptera: Chalcididae), with a review of the B. tibialis-group and description of a new species parasitizing Zygaena pupae (Lepidoptera: Zygaenidae)
The Brachymeria tibialis species group is newly recognized and diagnosed together with the Brachymeria annulata, femorata, kassiliensis and lasus species groups also newly defined. In these diagnoses a few morphological characters of the ventral part of the mesosoma, discovered in this study, are proposed to help differentiate the groups. The...Delvare, Gérard ; Shaw, Mark R

Rearings of four European Microgastrinae (Hymenoptera: Braconidae), three new to Britain including a new species of Cotesia Cameron, 1891
Cotesia carterocephali sp. nov. is described from a single gregarious brood reared from a posthibernation final instar larva of the hesperiid butterfly Carterocephalus palaemon in Scotland. Details of English rearings of two other Microgastrinae recorded from Britain for the first time are also given: Distatrix pompelon, gregariously from the erebiid... -

Biological and morphological studies on the parasitoids (Hymenoptera, Ichneumonidae) of Aprosthema tardum (Klug) (Hymenoptera, Argidae, Sterictiphorinae) in Var, southern France
Field surveys at four neighbouring but discrete sites in southern France revealed the presence of five ichneumonid parasitoids of the -feeding sterictiphorine argid sawfly . Four of these parasitoids, , (both Ctenopelmatinae), and (both Tryphoninae), could be identified and, by also incorporating laboratory studies, the developmental biology of each was... -

Identity of wasp parasitoids (Hymenoptera) attacking Pieris brassicae (Linnaeus, 1758) (Lepidoptera: Pieridae) in South Africa
The alien invasive large cabbage white, Pieris brassicae (Linnaeus, 1758) (Pieridae), although introduced into South Africa more than 27 years ago, has not dramatically expanded its distribution, possibly because it is effectively attacked by two parasitoid wasp species. Even though there is a cohort of parasitoid species associated with P.... -

Larval parasitism in a specialist herbivore is explained by phenological synchrony and host plant availability
Parasitism is a key factor in the population dynamics of many herbivorous insects, although its impact on host populations varies widely, for instance, along latitudinal and altitudinal gradients. Understanding the sources of geographical variation in host–parasitoid interactions is crucial for reliably predicting the future success of the interacting species under...Stefanescu, Constantí ; Colom, Pau ; Barea‐Azcón, José Miguel ; Horsfield, David ; Komac, Benjamin …

Evidence that Temminck described Felis aurata in 1825, not 1827
The African golden cat, Caracal aurata, ranges from west through central to east Africa and is categorized as Vulnerable on the IUCN Red List of Threatened Species. Coenraad J. Temminck (1778–1858) described Felis aurata (African golden cat) and other new felid species in the fourth of seven monographs collected in... -

The expensive-tissue hypothesis may help explain brain-size reduction during domestication
Morphological traits, such as white patches, floppy ears and curly tails, are ubiquitous in domestic animals and are referred to as the ‘domestication syndrome’. A commonly discussed hypothesis that has the potential to provide a unifying explanation for these traits is the ‘neural crest/domestication syndrome hypothesis’. Although this hypothesis has...Lesch, Raffaela ; Kotrschal, Kurt ; Kitchener, Andrew C ; Fitch, W Tecumseh ; Kotrschal, Alexander

Early Eocene fossil illuminates the ancestral (diurnal) ecomorphology of owls and documents a mosaic evolution of the strigiform body plan
We describe a partial skeleton of a fossil owl (Strigiformes) from the early Eocene London Clay of Walton-on-the-Naze (Essex, UK). The holotype of Ypresiglaux michaeldanielsi, gen. et sp. nov. is one of the most complete specimens of a Palaeogene owl and elucidates the poorly known ecomorphology of stem group Strigiformes....Mayr, Gerald ; Kitchener, Andrew C
